Thank you for replying, it's much appreciated. I did upgrade from earlier Tapestry versions as they were released. The code that fails was only added after the latest upgrade (5.3.3) so I can't say if it would fail on older versions. I made sure to clear browser cache and I also changed the SymbolConstants.APPLICATION_VERSION to ensure a new path for all scripts etc. I have tested that this error happens on 3 different PCs, so browser cache is really not likely to be the culprit.
I hadn't set the SymbolConstants.MINIFICATION_ENABLED, but changing SymbolConstants.PRODUCTION_MODE implicitly changes MINIFICATION_ENABLED accordingly and the error happens both in development and production mode. I did try both true/false for MINIFICATION_ENABLED afterwards, but same result. I also tested with "tapestry.compress-whitespace" true/false to see it that would make a difference, but no... Please note that the error only occurs when the form field's validate requirement is not met. This causes setSubmittingElement (tapestry.js, line 1545) to be called with null argument. This again adds a hidden null-value named "t:submit" to the form. The exception then happens in isFormCancelled() (Form.java, line 590) where the value of "t:submit" is literal "null" in IE 8/9 and not simply null as in Firefox/Chrome. Again, if someone could try out the simple Tapestry page below in 5.3.3 and IE 8/9, I would love to hear the result?

Did you just modify the class path from pointing to an older tapestry version to a newer one ? Please state your app configuration.
